Mature size, hardiness zones, sun and the trait tags were checked against named botanical sources for this plant. The bloom months and water need on this page were not.
Growing Angelonia
Plant it in full sun. It prefers moderate water. It is hardy in USDA zones 9–11. Expect it to reach about 1.5 ft tall and 12 in wide at maturity, in roughly 1 year.
When to plant Angelonia
Wait until all danger of frost has passed, then plant out Angelonia 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: for the middle of its range, start with zone 9 in February.

Good to know about Angelonia
Curated from university extensions, botanic gardens and other primary sources, with the source named on every note.
Worth knowing
Angelonia is an oil-flower: instead of nectar its blooms reward bees with fatty oil, and its true pollinators are specialized oil-collecting bees native to the American tropics. per PMC
Size depends on cultivar
Compact series (Serena, Serenita) stay about 0.25 to 0.45 m tall; taller series (AngelMist, Angelface) reach 0.6 to 0.9 m in hot southern gardens. Check the series. per NC State and Clemson
No deadheading needed
It is self-cleaning and flowers nonstop all season without deadheading. Shear leggy plants back by up to half in mid-season and they re-flower in about 2 to 3 weeks. per NC State
Thrives in heat and humidity
Its signature strength: it keeps flowering through hot, muggy summers that stall many bedding plants, thanks to its tropical and subtropical origin. per Clemson
Good drainage prevents root rot
Drainage is one lever: it is drought-tolerant once established and likes to dry between waterings, and soggy soil is exactly what invites phytophthora root and crown rot. per NC State
Not listed as toxic
Generally regarded as non-toxic: it appears nowhere on the ASPCA toxic-or-non-toxic plant lists, and the NC State entry carries no poison rating. per ASPCA and NC State

Good companions share its growing conditions and add something it lacks: an earlier or later bloom, a lower carpet in front, or structure through winter.

Perennial Sunflower
Shares full sun and moderate water; its seed heads stand through winter, for structure and the birds; both offer pollinator forage; taller at 4.9 ft, for the layer behind it.
Rosemary
Shares full sun and low to moderate water; blooms in early spring, before this one opens; both offer pollinator forage, in different months; evergreen, so the bed keeps its shape through winter.
Globe Thistle
Shares full sun and low to moderate water; its seed heads stand through winter, for structure and the birds; both offer pollinator forage; taller at 3.3 ft, for the layer behind it.
Lilac
Shares full sun and moderate water; blooms in mid spring, before this one opens; stands well above at 9.8 ft, a canopy to plant beneath; both offer pollinator forage, in different months.
