Serena Purple
Angelonia 'Serena Purple'
Serena Purple blooms from June through October.
Months here are Northern Hemisphere months; in the Southern Hemisphere, shift them by six months.
Growing Serena Purple
Plant it in full sun. It prefers moderate water. It is hardy in USDA zones 9–11. Expect it to reach about 16 in tall and 12 in wide at maturity, in roughly 1 year (a house reading).
No toxicity note is on file for Serena Purple. That is not a clearance: check its safety for people and pets before planting.
What was checked
Fifteen fields were checked against named botanical sources, each recorded beside the sources that carried it, with every unsettled point written down and decided: mature height and spread, hardiness zones, sun, water, bloom months and color, the trait tags, soil, diseases, pests, toxicity, the plant's own names, and years to mature size, which rests on a recorded house rule where no publisher states one and is marked so. Each fact above carries its own mark. The planting, spacing and size sections are derived from these checked facts by a fixed rule, not checked separately, and the plant type is the library's own classification.
When to plant Serena Purple
Wait until all danger of frost has passed, then plant out Serena Purple into warm soil; in most zones that means late spring. Planted then, it flowers from June to October.
Month-by-month timing for your zone is on the planting calendar; if you garden near zone 9, the middle of this plant's hardy range, start with zone 9 in February. Derived from the plant's category, zones and bloom months plus typical zone frost dates, not checked separately.

How far apart to plant Serena Purple
Derived from the mature spread above by a fixed rule, not checked separately: spacing is the spread, center to center.
Space Serena Purple about 12 in apart, center to center, so each plant has room to reach its full width.
Add Serena Purple to a garden plan and the planner draws it at its full width, so you see the spacing before you buy.
Where these facts come from
Serena Purple's height, spread, hardiness zones, sun, water, bloom months and color, trait tags, soil, diseases, pests and toxicity were checked against 15 published sources on August 24, 2026. Each one is linked below with every fact it carried, which can include a fact this page still marks as not yet checked, because a source carrying a value is not the same as the value being held to the standard. Facts not in that list, and the planting, spacing and size sections, are not covered by these sources.
