Amadeus Broccoli
✓ In your garden
Amadeus is a calabrese broccoli, ready in about 59 days. Cut the main head while the buds are still tight and green, and most types keep throwing smaller side shoots for weeks. It bolts in heat — grow it in spring or fall.
“A cool-season broccoli grown for its tender flower heads.”

Zone 6bGreenhouse or cover on: your start slides ~4 weeks earlier and your harvest stretches ~3 weeks later (shown striped).
Planting seeds straight in the ground only works where the season's long and warm — most gardeners start seeds indoors or buy young plants, or you'd pick your first tomato right as frost hits.
Comfortable — first ripe fruit lands around mid May, well before your typical frost (~late Oct).

What to plant near Amadeus — and what to keep away
-
Aromatic HerbsTrialed
Mixed, strong-smelling plantings make brassicas harder for pests to find — real research, modest effect. Keep mint in a pot.
-
DillTrialed
Dill flowers feed the tiny parasitoid wasps that hunt cabbage worms. Let some of it bloom near the bed.
-
Flea Beetle Trap StripTrialed
A trap strip pulls flea beetles off young seedlings. UMN found mixes of three-plus trap species beat any single one.
-
BeetsTraditional
On the classic chart's companion list for the cabbage family.
-
NasturtiumTraditional
On the WVU companion list, with an aphid-magnet reputation. If aphids pile on, pull those plants before they breed.
-
Onions & garlicTraditional
Old chart pairing; both hold cool-season beds.
-
PotatoesTraditional
Old chart pairing.
-
Beans PoleTraditional
Chart canon says no. Nobody's proven why. Cheap to respect.
-
StrawberryTraditional
Flagged on the classic charts, including WVU's. Mechanism murky; the canon is consistent.
-
TomatoTraditional
Flagged on the classic charts, mechanism murky. Skip the pairing if you've got the space.
The badge is the honesty. Trialed = a published field trial · Practical = a real mechanism · Traditional = companion-chart lore. These pairings hold for every broccoli.

Growing Amadeus — the things that trip people up
- Cut the main head while the buds are still tight and green — once yellow flowers open, it’s past its best. Most types then push side shoots for a second, smaller harvest.
- Brassicas are cool-season — they bolt or turn bitter in summer heat, so grow them in spring and fall. Feed them well and watch for cabbage worms (the little green caterpillars); a floating row cover keeps the moths off.
