Seasonal color tables

The spire, for one season

True delphiniums are plants of cool summers, and in Queen Creek they are grown for a single spring: set out in fall or late winter, they push up dense spikes of spurred flowers in March and April — ‘Delphina Pink White Bee’ in soft pink with a white center — and then decline in the heat. ‘Delphina’ is a dwarf series, around two feet, that stands without staking and suits a pot or the middle of a border. Treat it as a spring annual and it is a joy; treat it as a perennial and it will disappoint.

All parts are toxic to people, pets and livestock. The rest of the color tables are on our Annual Flowers & Foliage page.

Growing delphinium in the low desert

The care tag was written somewhere else. This is the Queen Creek version.

01

When to plant — October through February

Set out from mid-October through February. Fall plantings develop a strong crown and flower in March and April; February plantings of larger plants flower a few weeks later. It declines in May heat. Frost-hardy.

03

Soil and water

Rich, well-drained soil with compost, or a quality potting mix. Water every two to three days as the spikes rise, at the base — delphiniums are thirsty in flower and prone to crown rot if the base stays wet. Mulch, keeping it clear of the crown.

05

After the first spike

Cut the main spike back to the foliage when it fades and side spikes follow in two to three weeks, until the heat ends the show. Pull the plant in June, or try summering it in afternoon shade with sparing water — rarely successful here.

02

Sun

Full sun through winter; afternoon shade from April lengthens the bloom. It flops toward the light in shade.

04

Feeding and support

A balanced fertilizer at planting and a bloom fertilizer every two weeks once spikes appear. ‘Delphina’ usually stands on its own; a single stake helps in a windy spot.

06

Toxicity, pests and pets

All parts of delphinium are toxic to people, pets and livestock; plant it away from the vegetable garden and out of reach, and wash hands after handling. Aphids on buds, slugs after rain, powdery mildew at the end of the season.

Everything the flowers need

Annuals succeed or fail on what’s under them. We stock planting mix and compost for beds, potting mix for containers, bloom fertilizers including Tony’s Magic Mix and Magic Flower, starter fertilizer, drip fittings and frost cloth for the cold nights. The pottery yard has glazed and terracotta pots from 4-inch to whiskey-barrel size, window boxes and hanging baskets, and soil and mulch is sold by the bag or by the yard.

Every two to three days while it is growing and flowering, at the base, in well-drained soil.

Cut the spent spike back to the foliage and side spikes follow within a few weeks, until the heat arrives.

‘Delphina’ is a dwarf and usually stands alone. Stake in a windy spot.

Rarely. Afternoon shade and sparing water give it a chance; most plants are replaced in fall.
