Cummings, a former West Indies and Barbados seamer, bagged three wickets for 12 runs in four overs in the rain-affected showpiece that was reduced to 24 overs per side, at the picturesque KMV Oval in St Andrew on Saturday.
The result meant that Gladiola, formerly known as Cable & Wireless, BET, and LIME, are the double white-ball champions for the 2023-24 season, after they beat Bayview Hospital YMPC by five wickets to win the BCA Twenty20 Cup last June.
Scores: BWU-Super Blend Gladiola 294 all out (50 overs); Wildey 122 all out (17.5 overs)
Cummins produced a destructive opening spell which caused Wildey problems, and from there, the opponents in their chase of a revised target of 249 off 24 overs, struggled to get anywhere close.
Left-arm spinner Matthew Jones supported with two for 21 from 1.5 overs, and former Barbados and West Indies off-spinner Ashley Nurse captured two for 35 from five overs.
Carlos Maynard led the way for Wildey with 44, and his captain Jerome Jones made 21, but no other batsman reached 20.
Wildey were put under early pressure when Demetrius Richards, their most prolific batsman in the tournament, was caught at third man off Cummins for four, and United States batsman Aaron Jones was run out for a duck without facing a ball in a horrible mix-up with West Indies Under-19 batsman Joshua Dorne in the next over.
Cummins tightened the screws in his second over when he got Dorne caught behind for six, and former Barbados and West Indies all-rounder Carlos Brathwaite, surprisingly batting at five, endured a similar fate, when he fell for a four-ball duck in the third over from the pacer.
Wildey slumped to 17 for four and continued to bleed wickets around the two rain interruptions. Jones brought the match to a close when he trapped Deswin Currency leg-before-wicket for four with 37 balls remaining.
Earlier, Thomas struck two fours and two sixes in the top score of 62 off 76 balls, and De Peiza gathered 50 from 78 balls that included three fours and two sixes.
Thomas, who was dropped on 21 by Jayden Roberts in the 18th over, shared 85 for the second wicket with De Peiza that was the bedrock of the Gladiola total.
Left-hander Jones supported with 49 that helped him earn the Player-of-the-Match award, and former Barbados and West Indies Under-19 batsman Giovonte De Peiza made 35.
Wildey captain Jerome Jones was the pick of the bowlers for his side with three for 46 from 10 overs, and Brathwaite took three for 78 from 10 overs.
The Kings won the toss and chose to field first, quickly regretting that decision when the Capitals got off to a magnificent start with the bat.
After losing South African Hashim Amla early for 3, former India opener Gautam Gambhir and former West Indies batsman Kirk Edwards put on 107 for the second wicket before Gambhir fell for a 35-ball 63 in the 11th over.
Edwards went on to make the next highest score in the innings with 59 off 31 balls while Ben Dunk (37) and Ashley Nurse (34) also made solid contributions as the Capitals got what they thought would be a match-winning total of 228-8 off their 20 overs.
Anureet Singh took 4-29 from his four overs for the Kings.
Bhilwara’s opening pair of Lendl Simmons and Solomon Mire then put on only 22 for the first wicket before Simmons was first to go for 11.
It was quickly 27-2 when Tillakaratne Dilshan went for just one.
Mire and new batsman Robin Bist then put on 67 for the third wicket before Bist went in the 11th over for 30 leaving the Kings 94-3.
Mire was next to go, 40 runs and three overs later for a well-made top score of 70 from 40 balls including nine fours and three sixes.
Eventually, the Kings were 186-7 in the 18th over before captain Irfan Pathan performed a miracle to help them get over the line at 229-7 in 19.2 overs.
Pathan made 65* off just 19 balls including one four and nine sixes.
Isuru Udana took 3-51 from his four overs for the Capitals.

Powell hammered an even 100 off a mere 57 balls, which ensured that the Capitals chased down 164 with inside 18 overs at the Rajiv Gandhi International Cricket Stadium.
Scores: Southern Superstars 163-6 (20 overs); India Capitals 164-3 (17.4 overs)
The 44-year-old, who featured in two Tests and 109 One-Day Internationals for the West Indies, struck six fours and 10 sixes in the knock in which he raised his half-century in the ninth over after smashing seamer Ashok Dinda for 23 runs.
From there, things got easier for Powell, who partnered with former West Indies Test vice-captain Kirk Edwards in a 128-run, match-winning third wicket stand.
Edwards had five boundaries and a solitary six in his unbeaten 35-ball 45.
Earlier, Sri Lankan Chaturanga de Silva registered a 34-ball 56, while Shreevats Goswami and New Zealand’s Ross Taylor chipped in with 24 apiece, in getting the Superstars to what seemed a competitive total at that point.

Powell’s compatriot Chadwick Walton lashed 104 off 55 deliveries for Manipal Tigers in their encounter on Friday.
