Nasturtium

Tropaeolum majus

Round leaves and vibrant flowers for a relaxed trailing edge.

Make it part of your growing collection.

A LITTLE EVERYDAY CARE

Help it thrive.

A few things worth knowing.
01

Do not overfeed

Rich feeding encourages leaves but can reduce flowering. Poor to average, freely draining soil is usually a better fit.

02

Allow for the growth habit

Choose a bushy type for compact planting or leave room for climbing stems. Climbing varieties can cover a substantial area.

03

Watch for volunteers

Nasturtiums can self-seed and spread beyond their original spot. Keep an eye out for seedlings if you want a contained planting.

Data sources & uncertainty
Sunlight

Sun or partial shade is listed. 2+ hours is a broad category, not a yield guarantee.

Source · checked 2026-09-14
Moisture

A sufficiently specific moisture preference has not been verified; excluded from scoring.

Source · checked 2026-09-14
Soil pH

No precise numeric pH range verified. Broad acid/neutral/alkaline tags are not converted into invented bounds.

Source · checked 2026-09-14
Drainage

Free drainage is recommended; the ordinal distinction is an interpretation, not a measured drainage rate.

Source · checked 2026-09-14
Nutrients

No comparable numeric nutrient requirement verified; excluded from scoring.

Source · checked 2026-09-14
Soil texture

Listed or described textures are examples, not an exhaustive list of tolerances. Unlisted texture alone is not a hard exclusion.

Source · checked 2026-09-14
Plant spacing

Cultivar-dependent planning allowance, not a verified universal planting distance.

Source · checked 2026-09-14
Growing depth

Approximate planning value; cultivar, growth stage and container form change the requirement.

Source · checked 2026-09-14
Typical height

Approximate planning value; cultivar, growth stage and container form change the requirement.

Source · checked 2026-09-14
Growing season

Broad growth preference only; excluded from scoring because no location or planting date is known.
