About Lemon Drop Pepper

Capsicum baccatum 'Lemon Drop' · also called Lemon Drop pepper, aji limon · edible

Lemon Drop is a Peruvian aji (Capsicum baccatum) prized for bright, citrusy heat around 15,000-30,000 Scoville units. The tall, productive plants set crinkled yellow pods over a long season. It needs full sun, warm nights and a long frost-free spell, so most growers raise it from an early indoor sowing.

Cold limit: USDA 9-11 outdoors; grown as a frost-tender annual elsewhere · RHS H1c (21-30°C)

Watch for — Blossom drop: Flowers abort when nights stay above ~24°C or below ~13°C, or under drought stress; pods set again once temperatures and watering even out.

What lemon drop pepper's hardiness rating actually means

Hardiness works differently for lemon drop pepper: it is grown as a seasonal crop, not overwintered. The question is not "what zone" but "how long is your frost-free growing window". Its RHS rating of H1c means: Warm-temperate — can summer outdoors but must come in well before the first frost. On the US scale that maps to USDA 9-11 outdoors; grown as a frost-tender annual elsewhere — the zones where it can be left outdoors year-round.

Minimum temperature — and what happens below it

As an annual crop, its "minimum temperature" is the first hard frost — that is the end of the plant's life, not a survivable low. Many types are also damaged by light frost (around 0 °C).

Can lemon drop pepper go outside or overwinter — and where?

Work back from your local frost dates with the frost-date calculator: the last spring frost and first autumn frost are what really decide when lemon drop pepper can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1c figure above.

Lemon Drop Pepper hardiness — frequently asked questions

Is lemon drop pepper cold hardy?

As an annual crop, its "minimum temperature" is the first hard frost — that is the end of the plant's life, not a survivable low. Many types are also damaged by light frost (around 0 °C).

What hardiness zone is lemon drop pepper?

Can lemon drop pepper survive winter outside?

Time it to your frost dates: sow or plant out after the last spring frost, and aim to harvest before the first autumn frost. In short-season zones, start it indoors or under cover to stretch the effective growing window. Hardier crops in this group can be sown for an autumn or overwintered harvest in mild zones — check the specific crop.

How do I protect lemon drop pepper from frost?

Use fleece, cloches or a cold frame at each end of the season to dodge a borderline frost and add growing weeks. Have row cover ready for an unexpected late spring or early autumn frost. Know your local last- and first-frost dates and count back the crop’s days-to-maturity to schedule the sowing.
