Roses Blooming Wrong Color with Aggressive Canes: Rootstock Takeover

Second year 'Memorial Day' (soft pink) and 'Sunset Celebration' (pale orange) bloom as tiny 6-7 petal dark red flowers. After bloom, long smooth canes shoot in all directions, take over. Cut back 3 times in 4 months—no more blooms. All 5 plants affected.

Diagnosis: 'Dr. Huey' Rootstock Dominance

US grafted roses typically use 'Dr. Huey' (deep red climber) as rootstock. Harsh winter killed the grafted varieties. Rootstock sprouted from graft union—now the entire plant.

Why It Fooled the Owner

• Growth from existing cane structure, not base
• Smooth, vigorous canes typical of 'Dr. Huey'
• Single spring flush matches 'Dr. Huey' habit
• Dark red, small, low-petal-count flowers = 'Dr. Huey' signature

No Recovery

Original varieties dead. 'Dr. Huey' cannot revert. Options:

• Keep as hardy red once-blooming climber
• Replace with own-root versions (no rootstock)
• If replacing grafted: improve winter protection (12" mound over graft)

Identification Confirmation

'Dr. Huey' flowers: small, double, carmine red, once-blooming. Canes: smooth, green, very vigorous. Matches perfectly.
