Wednesday, we welcomed the official First Day of Spring.

Technically, spring arrived at 10:00 PM on Tuesday when the sun crossed the equator line, heading north, also known as the spring equinox.

Another way to put it, the First Day of Spring is when the entire world experiences an equal amount of daylight and darkness. It only happens twice per year, but right now we are not going to even think about the other time when the sun passes the equally headed south!

What a spring it has been! One of the brightest most can remember! Spring arrived early and just keeps on making a statement!

What defines spring for you?

For me spring is when shrubs and trees start blooming, bulbs are adding splashes of color, fescue lawns regain their rich green color, and warm seasons grasses start to break dormancy.

Spring is everything that is happening right now in the Oklahoma City area.

What are your favorite spring blooming plants?

Are you like me? Your favorite is, “All of them!”

PERENNIALS

Creeping Phlox. The first to welcome spring each year. Creeping phlox produces a spring-like carpet in pastel hues of white, lavender, red and pink. Creeping phlox is a moderate grower that can spread up to 2’ but only reaches 4-6” in height. It requires full sun but will tolerate a couple hours of shade each day. Borders, walls, and around boulders are where it looks best. In my garden, you will find it cascading over a rock retaining wall. It tolerates most soils if it is well drained. The plant requires little maintenance. Mites are about the only insect problem it will have.

Dianthus. It works well as a border, in small groupings, around boulders or as a single plant reaching 10-15” tall with a spread of 12-24”. They bloom in late spring in rose, pink, white, red. They like full sun but will take some dappled shade or afternoon shade. Just like creeping phlox, they are a cool season lover. They will grow in most soils, prefer alkaline soils, but waterlogged soil will cause crown and root rot. Heavy mulching near the crown of the plant can be detrimental. Late March through April and into May is the peak bloom time. Light feeding in the spring with a complete fertilizer of phosphorus, potassium and low nitrogen is recommended. Other an occasional aphid or powdery mildew issue, they do not have many problems. There are more than 300 varieties of dianthus to choose from. My all-time favorite is ‘Firewitch’. It has a silver-green foliage with a vibrant pink bloom.

SHRUBS

Forsythia. Best grown as a specimen shrub where it can show off its naturally stunning shape. Forsythia’s brilliant yellow flowers are the first to welcome spring. It performs best planted in full sun and will grow in partial shade, only with less spring blooms. It is considered a fast grower. Forsythia adapts well to most soils but prefers well drained. It rarely has an insect or disease problem. Pruning should only occur after spring blooms fade. If you prune later in the year, you will reduce blooms the following spring. The best way to prune this shrub is to remove older wood all the way to the base of the shrub. Traditional forsythia will grow to 6-8’ with an 8’ spread and are well suited for large lawns. If you have a smaller yard, look for one of the newer varieties, such as Gold Tide (Forsythia ‘Courtasol’), a dwarf variety that only reaches 2’ high and spreads to 4’.

Bridal Wreath Spirea. A medium sized shrub with arching branches covered with an abundance of white cascading flowers in mid spring. It is a very hardy, heirloom shrub, with no specific pest issues that thrives in well drained soils. It attracts hummingbirds and butterflies. To preserve the natural arching shape, avoid sheering but if pruning is needed, it is best done in the spring after blooms fade. It looks stunning planted in full sun to partial shade in front of darker structures or large hollies. Spiraea nipponica ‘Snow mound’ is another great variety.

Dwarf Flowering Almond. A somewhat temperamental shrub with wiry branches. But somehow when it is loaded with pink and white double flowers in early spring you only see it as the perfect plant in your landscape. They can become messy in appearance without annual pruning after the blooms drop in the spring. They prefer sun to partial shade and are tolerant of most soils as long as they are not too wet.

TREES

Redbud. My all-time favorite “Welcome to Spring” plant. (You can expect me to dedicate an entire email to this tree every spring.) Reddish-purple blooms appear on branches before leaves appear. The ‘Oklahoma’ variety was discovered in the Arbuckle Mountains and known for its glossy, heart shaped, green leaves in the summer. It grows to 15’-20’. Prefers full sun but does well as an understory tree in dabbled shade. For more Redbud love, visit our article from last week!

Bonfire Patio Peach. With a mature height of 5-6’, its profuse early spring eye-level pink blooms are a real head turner. The dark red to burgundy summer foliage keeps the interest going all season long. The small tree performs best if it receives at least 6 hours of full sunlight per day.

‘May Night’ Salvia. Sage type flower spikes of deep bluish-purple that will add color in April, May, and early June. The best flower show will be in full sun, but it will tolerate a little dappled shade each day. The plant grows 12-18” tall with flower spikes reaching 24”. The plant looks great in the middle of the garden planted behind creeping phlox or dianthus, and in front of Shasta daisy or Black-eyed Susan. The leaves often become tattered later in the summer and become dormant over the winter. Keep faded blooms removed to maximize bloom period and pruning the plants after blooming may result in a few fall blooms. In the early spring, before new growth emerges, remove the dormant foliage. Salvia tolerates clay soils but will struggle with root rot if the soil stays saturated.

Flowering Quince. Another early bloomer known for adding splashes of red to the landscape. It also performs best in full sun and tolerates partial shade but with fewer blossoms. Considered a moderate grower and mid-sized shrub, most varieties reach 4-5’. It does best if planted where it can grow to its natural size and shape. If pruning is required, only prune in the spring after blooms have faded. Flowering Quince is loved by butterflies and hummingbirds. The plant is very draught tolerant once it is established and it will tolerate most soils, but like most plants would enjoy well drained areas. Another variety, Chaenomeles speciossa Double Take Series has blooms that resemble camellias.

Flowering Quince buds are staring to pop.

Shrubs such as Double Play Candy Corn Spirea add interest to the spring landscape as their new foliage emerges.

Snowball Bush is another great spring show piece that is just starting to add interest to the landscape.

Crabapple. There are many varieties of crabapples, but ‘Prairifire’ is one of the best. It was the Oklahoma Proven tree of the year in 2007. It is disease resistant and not fazed by most of the problems with crabapples. Flowers of rose-pink cover the tree as soon as leaves emerge. Young leaves go from purple-red to dark green as they mature. Branches have red fruit in the winter. Mature, 20-25’, trees have a rounded top. Plant in full sun as a specimen tree or in a grouping. Water extra during periods of extreme heat or draught.

Ornamental Peach Trees add shades of pink to the March landscape.

Saucer Magnolia. A specimen type tree that reaches 15-20’. Large blooms put on a spectacular show on multi-trunk spreading branches. Blooms range from white to pink to purple. Best if planted in full sun. Plant away from radiant west or south heat where warm spring days may cause buds to develop too early only to be killed by a late freeze. They require regular deep watering in the summer months when leaves become tattered looking. It is best if their roots are protected with a layer of mulch to conserve water in the summer.

Spring Bulbs

One of my favorite ways to declare spring is Hyacinths, Daffodils and Tulips!

Last October we wrote about spring flower bulbs, “Plan Now. Plant Next Month. Enjoy Next Spring.”

If you were inspired and added spring flowering bulbs to their landscapes, you have been enjoying a spring full of color. Bulbs started blooming early and just keep adding color.

Open your calendar right now to October and write “Plan spring bulb planting!”
