About Gladiolus 'Purple Flora'

Gladiolus 'Purple Flora' · also called Purple Flora gladiolus, purple gladiola · flowering

Gladiolus 'Purple Flora' is a large-flowered sword lily with deep, velvety violet-purple florets ranked on tall summer spikes, prized as a dramatic cut flower. Plant corms 10-15 cm deep in spring in full sun and rich, free-draining soil, staggering plantings for succession. Stake the tall spikes and lift corms before frost where winters are cold.

Plant type: flowering

Watch for — Tall spikes topple: Large-flowered spikes are top-heavy and blow over easily. Stake each stem or grow in supported blocks in a sheltered position.

The reasons gladiolus 'purple flora' isn't blooming

Almost every non-blooming gladiolus 'purple flora' traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding gladiolus 'purple flora' a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get gladiolus 'purple flora' to flower

Maximise sun. Give gladiolus 'purple flora' the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for gladiolus 'purple flora' and get the feeding right with the gladiolus 'purple flora' fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Gladiolus 'Purple Flora' flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.
