Atlantis Baby Broccoli

Family: Brassicaceae Brassica

Sweet, tender florets arrive in a compact, jewel-like head—Atlantis Baby Broccoli delivers a silky, fine-crisp bite with a gentle, green-sweet flavor.

The heads are especially uniform for a broccolini type, with slender stems that stay pleasantly snappy and hold their color beautifully. Grow for fresh garden harvests and for quick, high-impact roasting, steaming, and vibrant sauces where its baby size shines most.

hot-steam or blanch-and-chill for a crisp, jewel-like texture

Frequently Asked Questions

What should I do if my Atlantis Baby Broccoli develops downy mildew or fuzzy gray growth?

Check the undersides of leaves for gray-purple fuzz and look for yellowing patches on top during cool, damp weather—this is common with downy mildew in brassicas. Remove the worst affected plants, improve airflow by spacing and pruning only if needed, and water at the soil line (not over the foliage). If it’s spreading, use a labeled fungicide for downy mildew on broccoli and reapply according to the label once conditions stay wet.

How often should I water Atlantis Baby Broccoli during the 45–55 day main growth period?

Aim for consistently moist soil with no puddles—water when the top 1 inch of soil feels dry. In warm spells, this usually means about 1–2 deep waterings per week, but in containers or sandy beds you may need more frequent checks to keep the root zone evenly moist. Mulch around plants to reduce rapid drying while still keeping the crown and lower leaves from staying wet.

How can I tell when Atlantis Baby Broccoli is ready to harvest?

Harvest when the main heads are tight and deep green, roughly 3–4 inches across for baby-sized heads, usually around 55 days after sowing/planting. If you see any loosening buds or any yellow flowers starting, harvest immediately to prevent bitterness. Cut the head 1–2 inches below the crown, then keep watering—side shoots often produce additional baby heads within the following 1–2 weeks.
